My cervical vertebra (61 years) pressure sensitive, with morgentlicher Unbweglichkeit not tolerate hard pillows. I found my pillow, height adjustment by herausnehmare plate also great. Latex is a great material and pillow also has a good ventilation, no more sweating. Those looking for a real support pillow is here too soft on the go. Have all new materials tried, all too hard, I'm happy to have found a latex pillow. Have it now for 4 weeks use, guard relaxed and movable on.
